The Q train was rated the top subway line for the first time since 2001 in part because of the most announcements and its above average rating in delays, seat availability and cleanliness. The 7 and J/Z lines tied for second.

The C train was rated the worst subway line by a wide margin and was worst or second to worst in scheduled service, delays, cleanliness and announcements. The 2, 4, A and B lines also rated low.

The E train had the fewest mechanical breakdowns, while the C had the most.

The 1 line had the cleanest cars while, you guessed it, the C had 25 percent of its cars with "heavy or moderate" dirt.

The 6 line had the most scheduled service, a train every 2.5 minutes, while the C had the fewest scheduled trains.

Overall, trains got dirtier. Ten percent of trains were viewed as unclean, as opposed to six percent in 2011.
